Patio Black Spot Preventer – 2.5 Litres

Patio Black Spot Preventer stops unsightly black or white spot infestation on patios, driveways and pathways.

Specifically formulated to work on black lichen spores, it will remove them before they germinate, which avoids the use of harmful pesticides. It also removes green algae after 3-5 days on stonework.

When used annually, Patio Black Spot Remover will also prevent re-infestation of fungal growth after it has been removed with Patio Black Spot Remover.
